DESCRIPTION
Digital DC/DC Controller
with PMBus Interface
The LTC7510 is a digital DC/DC controller with onboard
non-volatile memory and PMBus interface for real time
reporting and controlling of point-of-load (POL) power
management attributes such as current, voltage, and
operating frequency and temperature. Power supply se-
quencing, margining, turn-on/off are easily programmed via
the PMBus interface. The LTC7510 also provides extensive
POL fault detection reporting capability.
The LTC7510 uses a digital control loop to eliminate external
compensationcomponents.Thecontrollersupportscurrent
sharing of multiple ICs in high power designs. Up to four
controllers can be synchronized for multiphase operation.
The LTC7510 provides superior accuracy through internal
calibration that measures and corrects current sense er-
ror sources upon startup. Programmable current sense
temperature compensation allows the designer to tailor
the response for best accuracy over temperature. The
LTC7510 is available in the 32-lead QFN package.
